| 中文摘要: |
| 利用SRAP 标记对白鹤芋属23 份样品进行遗传多样性分析，30 个引物组合共扩增出343 个位
点，其中多态性位点为214 个，多态性比率达62%。通过 NTSYS 软件计算得到的样品间遗传相似系数介于
0.36～0.98，显示白鹤芋属资源间存在一定的遗传差异；根据SRAP 扩增结果，利用UPGMA 法构建树状聚
类图，聚类结果将23 份样品分为3 组。从分子水平分析白鹤芋属种质的遗传多样性和亲缘关系，为白鹤芋
属种质资源的有效利用和开发提供依据。 |
| 英文摘要: |
| The sequence related amplified polymorphism（SRAP）marker was used to analyze genetic
diversity of 23 samples of Spathiphyllum. Thirty primer pairs generated 343 bands，214 bands（62%）of which
were polymorphic ones. Revealed by NTSYS software，the SM coefficient of genetic similarity ranged from 0.36
to 0.98，which indicated that genetic basis was relatively abundance among the 23 Spathiphyllum resources. A
dendrogram was constructed based on SRAP data using UPGMA cluster method. The 23 samples of Spathiphyllum
were classified into 3 major groups. The genetic diversity and relationships of Spathiphyllum resources were studied
at molecular level for providing new molecular evidences of utilization and exploitation of germplasm resources of
Spathiphyllum. |
